This work has long been out of print. In fact, those few copies found in the last decade have often brought prices usually attached to rare books and curiosa. The original edition was first published by Macmillan in 1933. Mr. Starrett revised and enlarged the work for a University of Chicago edition in 1960. This is the first paperback edition. Throughout the world this book is still recognized as the definitive study of Sherlock Holmes. (back cover)
